ABSTRACT

This chapter discusses the linear theory of piezoelectric micropolar elasticity with polarization gradient in the case of quasi-electrostatic approximation. W. Nowacki has derived the linear theory of the piezoelectric micropolar thermoe-lasticity in the case of a quasi-static electric field. The chapter provides the equations for an isotropic material. It describes the reciprocity relations and new uniqueness results by using a method suggested by jesan, avoiding the use of the Laplace transform and the incorporation of the initial conditions into the equations of motion. The chapter considers a micropolar piezoelectric anisotropic body. The local field equation and the associated boundary conditions that govern motion are obtained by means of the generalized formulation of Hamilton’s principle, where the polarization gradient is added to the set of the independent constitutive variables.
